Example:
Horizontal RATe
Format parameter setting
HRAT <frequency in Hz>
<frequency in Hz> (floating point accepted)
typical min = 1000
typical max = 130000
HRAT?
<frequency in Hz> (floating point returned)
The HRAT command sets the line frequency. Pixel rate is equal
to the product: HTOT times HRAT. Frame rate is equal to the
quotient: HRAT divided by VTOT. Field rate is equal to the
product: SCAN times the frame rate. The HRAT? query returns
the current horizontal frequency setting.
The FMTU command instructs the generator to use the new
setting. The ALLU command updates hardware to the new setting
and redraws the test image.

Horizontal RESolution
Format parameter setting
HRES <pixels>
<pixels>
min = 16
max depends on VRES and model of generator
HRES?
<pixels>
The HRES command establishes the number of active pixels per
line. The HRES? query returns the current setting of HRES.
The ALLU command updates hardware to the new setting and
redraws the test image.
